(See also Fig. 6.) d. Usually the regeneration of the various partstakes place in a coordinated fashion, the pharyngesdeveloping in relation to the intestine, etc., and allparts in such a manner that normal, i. e., adaptive,relations are established. Fig. 7 shows an excep-tion to this rule. The part figured was as nearlyas possible a 3^2 P^^^ of a normal individual; theindividual in question was divided into sixteenequal transverse pieces, and each of these was cutthrough its of these parts re-generated
